Mr. Zhu's speed is not fast, and he has no intention of making a shuttle bus, the closer he gets to the teaching building, the slower his speed becomes, and sometimes he even stops and looks left and right, as if he is looking for something or someone.

Several times, Teacher Zhu turned around halfway and scared Gu Wenyu who was following behind her, with such a sharp gaze, if it weren't for Gu Wenyu's body against the black cat, she would almost suspect that she was exposed.

Although Teacher Zhu did not doubt the black cat, Gu Wenyu still consciously distanced himself from Teacher Zhu.

A little black cat hidden under a dim street lamp, as long as you don't look carefully, you won't notice it at all.

From the dormitory to the teaching building, the distance is quite far, Gu Wenyu has to suspect that the cat is alive when she leaves, and at this moment, she even feels that the wounds on her two paws are going to burst again.

Originally, the wounds on Gu Wenyu's hands had just been removed, and when he was Shen Qing, he didn't know why, but he couldn't see the three wounds, but after turning into a black cat, the three centipede-like wounds reappeared.

It's just a small range of activities, but she has been walking with Teacher Zhu for more than half an hour, and although the wound hasn't really collapsed, it really hurts.

Just when Gu Wenyu was hesitating whether to continue to follow, Teacher Zhu finally stopped outside the No. 2 teaching building, which was the same building where Gu Wenyu had English classes in the afternoon.

Gu Wenyu stopped from afar, she didn't know what Teacher Zhu was doing in Building No. 2, could it be that she forgot something in the afternoon and came back to get it now?

If Teacher Zhu really came back to get something, then Gu Wenyu would probably be crying and fainting here. I followed all the way, but people just came back to get things.

But if you think about it, tracking this kind of thing should have been prepared for no gain. It is reasonable not to keep up, and it is an unexpected gain to follow.

Gu Wenyu came, so he naturally waited patiently to the side to see what Teacher Zhu was going to do.

She waited for a while and found that Teacher Zhu didn't mean to enter Building No. 2, he was just standing under the teaching building, looking up, as if he was looking at something from afar.

Gu Wenyu followed Teacher Zhu's gaze and looked up, only to see a window with lights on, there was nothing special about it, and he didn't know what Teacher Zhu was looking at.

After waiting for a while, Mr. Zhu finally moved.

Gu Wenyu also hurriedly followed, but Teacher Zhu did not enter the teaching building, but walked along the outer wall of the teaching building, he walked very slowly, kept his head down and looked left and right, and sometimes looked at the wall seriously, as if he was looking for something.

After walking in a circle, it turned out that another half an hour had passed.

Teacher Zhu probably didn't find what he was looking for, so he went back to the front of the teaching building and sat down on a bench by the flower bed.

Gu Wenyu squatted behind the tree, poked out his little head, and observed Teacher Zhu's every move from a distance.

After Mr. Zhu sat down, he took out his mobile phone and swiped it, looking normal, as if he was waiting for someone here.

Gu Wenyu is full of question marks, and Mr. Zhu's behavior tonight can be said to be very strange.

Although he didn't know what he was going to do, if Gu Wenyu wanted to believe that Mr. Zhu was just here to wait for someone, at the beginning, Gu Wenyu could still believe it, but at this point, he couldn't believe it if he killed Gu Wenyu.

A person and a cat sat not far away, and suddenly, Gu Wenyu caught a trace of undetectable demonic energy in the air, just for a moment, and then disappeared. No matter how Gu Wenyu smelled it, she didn't smell any demonic energy, so much so that Gu Wenyu couldn't help but wonder if she had a delusion.

Continuing to stare at Mr. Zhu, he seemed to grow on a chair, sitting there without moving, as if he had come to play with his mobile phone downstairs in the teaching building.

Gu Wenyu yawned boredly, she was so bored, and she didn't have a mobile phone to play, so she stared at Teacher Zhu intently, and she didn't dare to fall asleep.

She swears that stalking people is definitely a physical task, and she will never play like this again next time.

Although Gu Wenyu would soon break her oath, at this moment, her heart was broken, and she firmly believed that she didn't want to follow anyone anymore.

"Ding Ding Ding ~" The bell rang, and it was time for evening self-study.

The students walked out of the teaching building one after another, and Gu Wenyu jumped into the grass pile on the side of the road as soon as he saw that there were many people. She continued to stalk in the haystack, but found that Teacher Zhu was still swiping her phone.

It looks like a student waiting for his girlfriend to get out of class, and no one notices him. Teacher Zhu sat quietly, looking like he had been quiet for years.

But it was miserable for Gu Wenyu, although no one noticed her, but there were a lot of small insects in the grass, and she kept flicking her tail, but she was still unbearable.

Although Teacher Zhu had a face exactly the same as Gu Wentian, this did not prevent Gu Wenyu from scolding him thousands of times in his heart.

Finally, the students were almost gone, the front of the school building gradually became deserted, and then looking at Building 2, there were only a few windows with lights on.

Teacher Zhu finally moved, he put away his mobile phone, and stood up at the same time, he silently looked at Building No. 2, his eyes were extremely clear.

This time, Mr. Zhu did not hesitate, but went directly into Building No. 2.

Gu Wenyu waited for Teacher Zhu to go in for a while, and then slipped in while no one was paying attention.

There was no one on the first floor, obviously they came in with their front and back feet, and Gu Wenyu just lost the person. Where was she willing, since there was no one on the first floor, she went directly to the second floor.

The corridor on the second floor was quiet, there was no sound of footsteps, and there was a classroom with lights on, so Gu Wenyu slipped over and glanced outside the classroom.

There were four or five students in the classroom who were still studying on their own, and Teacher Zhu was not inside.

Gu Wenyu went up the stairs to the third floor again, and as soon as he stepped on the steps of the third floor, Gu Wenyu paused. This time, she was sure she smelled the demonic aura.

There was a demonic aura in the teaching building, why did she just stay downstairs for so long and didn't notice it?

Teacher Zhu came to the teaching building at this time, is it also related to this trace of demonic energy?

Gu Wenyu knew that this was definitely not a coincidence, and Teacher Zhu must know something.

Since she lost Teacher Zhu, she simply followed the demonic qi and went to find the source of the demonic qi first.

Gu Wenyu tried to distinguish the disgusting rancid smell in the air, followed the smell all the way up, and soon came to the eighth floor.

The highest floor of Building 2 is the eighth floor, but the source of this demonic energy is not here, it should be higher.

But if you go any further, you can't go up at all. This is the school building, and the door to the rooftop is locked all year round for security reasons.
